New Radiant Floor Heat -- Huge Problem

I've recently installed a radiant floor heating system to replace my old baseboard water heat. I was able to run all the tubing between the 16" joists and tak them up using aluminum plates. Here's the issue, the expansion of my PEX tubing is tearing down those plates daily; as well as causing a loud ticking sound coming from the floor as the tubing slowly creeps. I really could use a solution for this, it's mid winter and I have not yet finished insulating the system because I know I need to address this problem. Please help!

Under Floor Radiant

Let me preface my comments by saying I have never done an under floor system. My understanding of the plates is that the tubing is supposed to slide within the channel of the plate.
I suggest you contact the manufacturer for some guidance.
